Roy Spencer, Ph.D. Meteorology: Hurricane Florence is not the result of global warming. It's likely due to natural weather patterns, not climate change as some have already said. Coastal lake sediments along the Gulf of Mexico shoreline from 1,000 to 2,000 years ago suggest more frequent and intense hurricanes than occur today. Why? No one knows. Unusual things happen in nature sometimes. The Massachusetts Bay Colony in 1635 experienced a Category 3 or 4 storm, with up to a 20-foot storm surge. While such a storm does not happen in New England anymore, it happened again there in 1675, with elderly eyewitnesses comparing it to the 1635 storm.

Roy Spencer, Ph.D. Meteorology: The total amount of CO2 humans have added to the atmosphere in the last 100 years has upset the radiative energy budget of the Earth by only 1%. How the climate system responds to that small ‘poke’ is very uncertain. Here’s a list of basic climate change questions, and brief answers based upon what I know today.

Roy Spencer, Ph.D. Meteorology: Given current technologies, it makes no sense to destroy $100 Trillion in wealth this century for an unmeasurable reduction in warming. As a lukewarmist I believe (but can’t prove) that humans are probably responsible for some of the recent warming (which has been mostly benign). But until some new energy technology comes along we are stuck with fossil fuels for the foreseeable future. The oil industry’s use of fracking has already reduced carbon dioxide emissions — through a switch from coal to natural gas.

CO2 Coalition, www.co2coalition.org: Mark Twain said, "It is not so much the things we don’t know that get us into trouble. Rather, the mischief is caused by things that we do know that ain’t so.” We “know” that carbon dioxide is “bad for the environment.” (In fact, it is a prerequisite for life.) We “know” that the level of carbon dioxide in the atmosphere is reaching historically dangerous levels. (In fact, we have, these past centuries, been living through a CO2 famine. We “know” that on the subject of climate change, the “science is settled”.
